To all whom, t 'may concern.'

Be it known thatIJl:nEMmH BoHAN, a citizen of the United States, and a resident of New Hartford, inthe county of Butler and State of Iowa, have invented a new and useful Improvement in Motor-Vehicles, of which the following is a specification.

My invent-ion is an improvement in motor vehicles, and the invention has for its ol)- ject to provide mechanism in connection with motor vehicles 'of every character. for `ipplying the power of the motor directly to the four wheels. without interference with the steering of the vehicle.

furtherobject is to provide mechanism in connection with the front axle for steering thev vehicle. b v swinging the axle` thus dispensing with the usual pivoted spindle, and providing for greater strength in the axle.

In the drawings r-Figure 1 is a top plan view of a motor vehicle provided with the improvement. Figs. 2. 1, 5 and 6 are sections on the lines 2 2. and 6 6 respectively of Fig. 1. each looking in the direction of the arrow adjacent the line` Fig. 3 is a bottom plan view of the front-,of the vehicle. and Fig. 7 is a section on theline 7-7 of Fig. 2.

The present embodiment of the invention is shown in connection with a motor vehicle having a frame of substantially rectangular form and consisting of parallel side mem bers -1 and connected end members 2, the said side and end members being T-shaped in cross sect-ion as shown. A front axle is arranged transversely of the front end of the frame. and a rear axle 4 is arranged transversely of the rear end of the frame. lVheels are mounted on the ends of the axle i'n a manner to be presently described. and a driving shaft 5 is journaled transverse-ly of the frame at the center thereof in sectional bearings 7. which are secured to the side members 1, of the frame.

The rear axle is journaled in bearings 8 on the side members 1 of the frame. and both axles as shown are polygonal in cross section` square in the present instance, portions of the axles being rounded at the bearings for'permitting them to turn freely in the bearings. .The front axle 3 is journaled iu sectional bearings 9 on a ring 10. the saidA axle being arranged diametrically of the ring. and this ring is mounted to move or to revolve on a ring 11, which is secured to other end underlies the ring 10, holding the said ringr in contact with'the ring 11. but

Ipermitting the ring 10 to move angularly with respectl to the ring 11.

It will be understood that if desired ball or roller bearings may be arranged between the. rings. and it will be evident 'from the descrlption that when the ring 10 is turned with respect to the ring 11, the axle wil-l also be turned a-ngularly with respect tothe long axisof the' frame. Counter shafts 13 and 1t are journaled on the frame transversely thereof. the shaft 13being adjacent tothe front axle` and the shaft 14 being a'djacent to the rear axle. The 'shaft 13 is jonrnale-d in sectional bearings'l on the ring 11. the said shaft being insidethe vertical rib of the ring. The counter shaft 1.1L

is journaled in `sectional bearings 16 on the side members of the frame. and this shaft 1i is connected tothe axle 4; by'means'of gear wheelsl 1T and 1S on the axle and' onthe counter shaft respectively and meshing with each other. A gear wheel 19-is arranged on the counter shaftl. and this gear wheel meshes with a gear wheel 2O on the front axle. ln the present instance, the gear wheels- 1T. 1S. 19 and 20 have polygonal openings fitting the shaftsa'nd axles. so that they will turn with the shafts and axles, but it is obvious that they might be geared to the shafts and axles` or otherwise held in place. if found desirable or advisable. 'Suitable means is also provided 'for preventing longitudinal movement of the gea-rs -with respect to the shafts and axles. and it will be noticed from an inspection of Figs. 1 and 3. that the gear '20 is recessed peripherally on a n arc, whose center is the center of the gear wheel 19. the arrangement beingI such that' the axle or gear wheel may move angularly with respect to the counter shaft 13er gear wheel 19 without causing the gear Wheels to bind or become disengaged. and to secure contact between thegear wheels. whatever the position of the axlewith respect to the frame.

Sprocket wheels 21 and 22 are secured to the front and the rear axles respectively. and these wheels are connected byl chains 23 and The ring 11 is T-shaped in 'llvrrplzinn that when the driving shaft I :lr'nvn in thv mnnl inzmncr from the motor th@ ro.: \r axle tl'xrQugh-'the-'gears17'and '18; wh'lle the cuntrshaft V13.
